  • How can I prevent 'objects you are adding to the designer use a different data connection...'?

    - by Timothy Khouri
    I am using Visual Studio 2010, and I have a LINQ-to-SQL DBML file that my colleagues and I are using for this project. We have a connection string in the web.config file that the DBML is using. However, when I drag a new table from my "Server Explorer" onto the DBML file... I get presented with a dialog that demands that do one of these two options: Allow visual studio to change the connection string to match the one in my solution explorer. Cancel the operation (meaning, I don't get my table). I don't really care too much about the debate as why the PMs/devs who made this tool didn't allow a third option - "Create the object anyway - don't worry, I'm a developer!" What I am thinking would be a good solution is if I can create a connection in the Server Explorer - WITHOUT A WIZARD. If I can just paste a connection string, that would be awesome! Because then the DBML designer won't freak out on me :O) If anyone knows the answer to this question, or how to do the above, please lemme know!

  • What is the best practice for ouputting data from a collection on an ASP.net Page?

    - by bshacklett
    I've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code: <% Dim objs as ArrayList = New ArrayList() For i = 0 To 2 Dim obj as Obj = New Obj() obj.setProp1("ASDF") obj.setProp2("FDSA") objs.Add(obj) Next i %> <table> <thead> <tr> <th scope="col">Property 1</th> <th scope="col">Property 2</th> </tr> </thead> <tbody> <% For Each obj As Obj In objs Dim objProp1 As String = obj.getProp1 Dim objProp2 As String = obj.getProp2 %> <tr> <td><% Response.Write(objProp1)%></td> <td><% Response.Write(objProp2)%></td> </tr> <% Next %> </tbody> </table> What is the ".net" way of doing this?

  • ASP.NET MVC - Data Annotations - Why add a default RequiredAttribute?

    - by redsquare
    Can anyone explain why it is assumed that a non nullable type property should always have a RequiredAttribue? I am trying to write a label helper that will auto append * or change the css class so that I can indicate to the user that the field is required. However when querying the metadata the non nullable properties end up with a required attribute. MVC Source Code: protected override IEnumerable<ModelValidator> GetValidators( ModelMetadata metadata, ControllerContext context, IEnumerable<Attribute> attributes) { _adaptersLock.EnterReadLock(); try { List<ModelValidator> results = new List<ModelValidator>(); if (metadata.IsRequired && !attributes.Any(a => a is RequiredAttribute)) { //******* Why Do this? attributes = attributes.Concat(new[] { new RequiredAttribute() }); } foreach (ValidationAttribute attribute in attributes.OfType<ValidationAttribute>()) { DataAnnotationsModelValidationFactory factory; if (!_adapters.TryGetValue(attribute.GetType(), out factory)) factory = _defaultFactory; results.Add(factory(metadata, context, attribute)); } return results; } finally { _adaptersLock.ExitReadLock(); } }

  • How to debug jQuery ajax POST to .NET webservice

    - by Nick
    Hey all. I have a web service that I have published locally. I wrote an HTML page to test the web service. The webservice is expecting a string that will be XML. When I debug the web service from within VS everything works great. I can use FireBug and see that my web service is indeed being hit by they AJAX call. After deploying the web service locally to IIS it does not appear to be working. I need to know the best way to trouble shoot this problem. My AJAX js looks like this: function postSummaryXml(data) { $.ajax({ type: 'POST', url: 'http://localhost/collection/services/datacollector.asmx/SaveSummaryDisplayData', data: { xml: data }, error: function(result) { alert(result); }, success: function(result) { alert(result); } }); The web method looks like so: [WebMethod] public string SaveSummaryDisplayData(string xml) { XmlDocument xmlDocument = new XmlDocument(); xmlDocument.LoadXml(xml); XmlParser parser = new XmlParser(xmlDocument); IModel repository = new Repository(); if(repository.AddRecord("TestData",parser.TestValues)) { return "true"; } return "false"; } } I added the return string to the web method in an attempt to ensure that the web-service is really hit from the ajax. The problem is this: In FF the 'Success' function is always called yet the result is always 'NULL'. And the web method does not appear to have worked (no data saved). In IE the 'Error' function is called and the response is server error: 500. I think (believe it or not) IE is giving me a more accurate indication that something is wrong but I cannnot determine what the issue is. Can someone please suggest how I should expose the specific server error message? Thanks for the help!

  • Correct use of WSDL-generated sources

    - by John K
    How can I easily convert between manually written classes and WSDL-generated equivalents? I have a Java SE 6 thick client that calls a web service to get and store data. The client has a DAO that works with my entity classes, calls <Entity.toDto() to convert them to DTOs, and sends/receives that data with the web service. My issue stems from the fact that the entity classes live on both sides of the service interface: client and server. Each entity has a constructor from the DTO and a toDto function: public class EntityClass { public EntityClass(EntityClassDto dto); public EntityClassDto toDto(); ... } This means I have a handwritten DTO class that the client and server both use. However, the service interface expects the WSDL-generated classes. I have tried writing conversion code between the hand-written DTO and the WSDL-generated DTO and it is tedious and error-prone. What is a reasonable alternative to this? Some back-story: The thick client should be able to have a configurable backend: either direct to the DB or through this web service. The aforementioned DAO is the web service based implementation and another imlpementation that is JPA-based exists.

  • How to convert many-to-one XML data to DataSet?

    - by TruMan1
    I have an XML document that has a collection of objects. Each object has a key/value pair of label and value. I am trying to convert this into a DataSet, but when I do ds.ReadXml(xmlFile), then it creates two columns: label and value. What I would like is to have a column for each "label" and the value to be part of the row. here is my sample of the XML: <responses> <response> <properties id="1" Form="Account Request" Date="Tuesday, March 16, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain1.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="2" Form="Account Request" Date="Tuesday, March 17, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John2</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain2.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="3" Form="Account Request" Date="Tuesday, March 18, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John3</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain3.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> <response> <properties id="4" Form="Account Request" Date="Tuesday, March 19, 2010 5:04:26 PM" Confirmation="True" /> <fields> <field> <label>Name</label> <value>John</value> </field> <field> <label>Email</label> <value>[email protected]</value> </field> <field> <label>Website</label> <value>http://domain4.com</value> </field> <field> <label>Phone</label> <value>999-999-9999</value> </field> <field> <label>Place of Birth</label> <value>Earth</value> </field> <field> <label>Misc</label> <value>Misc</value> </field> <field> <label>Comments</label> <value /> </field> <field> <label>Agree to Terms?</label> <value>True</value> </field> </fields> </response> </responses> How would I convert this to a DataSet so that I can load it into a gridview with the columns: Name, Email, Website, Phone, Place of Birth, Misc, Comments, and Agree to Terms? Then row 1 would be: John, [email protected], http://domain1.com, 999-999-9999, Earth, Misc, , True How can I do this with the XML provided?

  • JsonParseException on Valid JSON

    - by user2909602
    I am having an issue calling a RESTful service from my client code. I have written the RESTful service using CXF/Jackson, deployed to localhost, and tested using RESTClient successfully. Below is a snippet of the service code: @POST @Produces("application/json") @Consumes("application/json") @Path("/set/mood") public Response setMood(MoodMeter mm) { this.getMmDAO().insert(mm); return Response.ok().entity(mm).build(); } The model class and dao work successfully and the service itself works fine using RESTClient. However, when I attempt to call this service from Java Script, I get the error below on the server side: Caused by: org.codehaus.jackson.JsonParseException: Unexpected character ('m' (code 109)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') I have copied the client side code below. To make sure it has nothing to do with the JSON data itself, I used a valid JSON string (which works using RESTClient, JSON.parse() method, and JSONLint) in the vars 'json' (string) and 'jsonData' (JSON). Below is the Java Script code: var json = '{"mood_value":8,"mood_comments":"new comments","user_id":5,"point":{"latitude":37.292929,"longitude":38.0323323},"created_dtm":1381546869260}'; var jsonData = JSON.parse(json); $.ajax({ url: 'http://localhost:8080/moodmeter/app/service/set/mood', dataType: 'json', data: jsonData, type: "POST", contentType: "application/json" }); I've seen the JsonParseException a number of times on other threads, but in this case the JSON itself appears to be valid (and tested). Any thoughts are appreciated.

  • zlib memory usage / performance. With 500kb of data.

    - by unixman83
    Is zLib Worth it? Are there other better suited compressors? I am using an embedded system. Frequently, I have only 3MB of RAM or less available to my application. So I am considering using zlib to compress my buffers. I am concerned about overhead however. The buffer's average size will be 30kb. This probably won't get compressed by zlib. Anyone know of a good compressor for extremely limited memory environments? However, I will experience occasional maximum buffer sizes of 700kb, with 500kb much more common. Is zlib worth it in this case? Or is the overhead too much to justify? My sole considerations for compression are RAM overhead of algorithm and performance at least as good as zlib.

  • How do bind a List<object> to a DataGrid in Silverlight?

    - by Ben McCormack
    I'm trying to create a simple Silverlight application that involves parsing a CSV file and displaying the results in a DataGrid. I've configured my application to parse the CSV file to return a List<CSVTransaction> that contains properties with names: Date, Payee, Category, Memo, Inflow, Outflow. The user clicks a button to select a file to parse, at which point I want the DataGrid object to be populated. I'm thinking I want to use data binding, but I can't seem to figure out how to get the data to show up in the grid. My XAML for the DataGrid looks like this: <data:DataGrid IsEnabled="False" x:Name="TransactionsPreview"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Date" Binding="{Binding Date}" /> <data:DataGridTextColumn Header="Payee" Binding="{Binding Payee}"/> <data:DataGridTextColumn Header="Category" Binding="{Binding Category}"/> <data:DataGridTextColumn Header="Memo" Binding="{Binding Memo}"/> <data:DataGridTextColumn Header="Inflow" Binding="{Binding Inflow}"/> <data:DataGridTextColumn Header="Outflow" Binding="{Binding Outflow}"/> </data:DataGrid.Columns> </data:DataGrid> The code-behind for the xaml.cs file looks like this: private void OpenCsvFile_Click(object sender, RoutedEventArgs e) { try { CsvTransObject csvTO = new CsvTransObject.ParseCSV(); //This returns a List<CsvTransaction> and passes it //to a method which is supposed to set the DataContext //for the DataGrid to be equal to the list. BindCsvTransactions(csvTO.CsvTransactions); TransactionsPreview.IsEnabled = true; MessageBox.Show("The CSV file has a valid header and has been loaded successfully."); } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void BindCsvTransactions(List<CsvTransaction> listYct) { TransactionsPreview.DataContext = listYct; } My thinking is to bind the CsvTransaction properties to each DataGridTextColumn in the XAML and then set the DataContext for the DataGrid to the List<CsvTransaction at run-time, but this isn't working. Any ideas about how I might approach this (or do it better)?

  • Generic structure for performing string conversion when data binding.

    - by Rohan West
    Hi there, a little while ago i was reading an article about a series of class that were created that handled the conversion of strings into a generic type. Below is a mock class structure. Basically if you set the StringValue it will perform some conversion into type T public class MyClass<T> { public string StringValue {get;set;} public T Value {get;set;} } I cannot remember the article that i was reading, or the name of the class i was reading about. Is this already implemented in the framework? Or shall i create my own?

  • How will a search engine read data from my Ajax-based webapp?

    - by Jack W-H
    OK, not entirely related to programming, so I'm sorry. But I'd like to know about this: So I've got a webapp. There's one column where a list of results are fetched from the database. When you click one, jQuery fetches the information associated with that result and puts it into the second column - all without a refresh and using Ajax. Is it possible for Google to still read it etc.? I understand it can follow links... but presumably not Javascript actions etc.? If this is the case, what do other Ajax-heavy websites do about search engine optimisation? Jack

    I have a simple search php script, within that script there is some html and javascript to make a search input field and a button. What i am trying to do is when someone enters a search, and presses submit, thickbox opens, and the results will be displayed in the thickbox. What i have so far is the search field and button, when i press submit, it briefly shows the thickbox, and than is overloaded by the result page, but than with no search results.

  • A format for storing personal contacts in a database

    - by Gart
    I'm thinking of the best way to store personal contacts in a database for a business application. The traditional and straightforward approach would be to create a table with columns for each element, i.e. Name, Telephone Number, Job title, Address, etc... However, there are known industry standards for this kind of data, like for example vCard, or hCard, or vCard-RDF/XML or even Windows Contacts XML Schema. Utilizing an standard format would offer some benefits, like inter-operablilty with other systems. But how can I decide which method to use? The requirements are mainly to store the data. Search and ordering queries are highly unlikely but possible. The volume of the data is 100,000 records at maximum. My database engine supports native XML columns. I have been thinking to use some XML-based format to store the personal contacts. Then it will be possible to utilize XML indexes on this data, if searching and ordering is needed. Is this a good approach? Which contacts format and schema would you recommend for this? Edited after first answers Here is why I think the straightforward approach is bad. This is due to the nature of this kind of data - it is not that simple. The personal contacts it is not well-structured data, it may be called semi-structured. Each contact may have different data fields, maybe even such fields which I cannot anticipate. In my opinion, each piece of this data should be treated as important information, i.e. no piece of data could be discarded just because there was no relevant column in the database. If we took it further, assuming that no data may be lost, then we could create a big text column named Comment or Description or Other and put there everything which cannot be fitted well into table columns. But then again - the data would lose structure - this might be bad. If we wanted structured data then - according to the database design principles - the data should be decomposed into entities, and relations should be established between the entities. But this adds complexity - there are just too many entities, and lots of design desicions should be made, like "How do we store Address? Personal Name? Phone number? How do we encode home phone numbers and mobile phone numbers? How about other contact info?.." The relations between entities are complex and multiple, and each relation is a table in the database. Each relation needs to be documented in the design papers. That is a lot of work to do. But it is possible to avoid the complexity entirely - just document that the data is stored according to such and such standard schema, period. Then anybody who would be reading that document should easily understand what it was all about. Finally, this is all about using an industry standard. The standard is, hopefully, designed by some clever people who anticipated and described the structure of personal contacts information much better than I ever could. Why should we all reinvent the wheel?? It's much easier to use a standard schema. The problem is, there are just too many standards - it's not easy to decide which one to use!

  • BroadcastReceiver not triggered by Alarm

    - by Ezekiel Buchheit
    I am trying to set up an alarm that will run in the background and trigger (eventually) a save event. At the moment I simply have this code attached to a button. Press the button and the alarm should start leaving Toast messages behind as an indication that it is functioning. At the moment everything runs except the onReceive in the BroadcastReceiver is never triggered. Here is my code: The class setting up the alarm: //FIXME - rename (ie BackgroundSave; more descriptive) public class AlarmReceiver extends Service{ //FIXME - make sure you kill the service public void onCreate() { super.onCreate(); Toast.makeText(getApplication().getApplicationContext(), "Service onCreate called", Toast.LENGTH_SHORT).show(); } @Override public int onStartCommand(Intent intent, int flags, int startId) { Toast.makeText(getApplication().getApplicationContext(), "Service started", Toast.LENGTH_SHORT).show(); setAlarm(AlarmReceiver.this); // We want this service to continue running until it is explicitly // stopped, so return sticky. return START_STICKY; } public void setAlarm(Context c) { AlarmManager alarmManager = (AlarmManager)c.getSystemService(Context.ALARM_SERVICE); Intent i = new Intent(c, Alarm.class); PendingIntent pi = PendingIntent.getBroadcast(c, 0, i, 0); alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, System.currentTimeMillis() + 1000, 1000, pi); Toast.makeText(c.getApplicationContext(), "setAlarm called", Toast.LENGTH_SHORT).show(); } public void cancelAlarm(Context context) { Intent intent = new Intent(context, Alarm.class); PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); alarmManager.cancel(sender); } @Override public IBinder onBind(Intent arg0) { // TODO Auto-generated method stub return null; } } Here is the BroadcastReceiver: public class Alarm extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "Alarm", Toast.LENGTH_SHORT).show(); } } And here is my manifest: <!-- Alarm --> <service android:name="com.xxxx.android.tools.AlarmReceiver" android:enabled="true" /> <receiver android:name="com.xxxx.android.tools.Alarm" ></receiver> The alarm onReceive is never triggered.

The code in question is as follows: public static void Main() { object myObject = new TestGeneric<string>("test"); // or from another source if (IsSubclassOfRawGeneric(typeof(TestGeneric<>), myObject.GetType())) { // the following gives an InvalidCastException // var data = ((TestGeneric<object>)myObject).Data; // if i try to access the property with reflection // i get an InvalidOperationException var dataProperty = typeof(TestGeneric<>).GetProperty("Data"); object data = dataProperty.GetValue(myObject, new object[] { }); } } I need the Data regardless of its type (well, if i could ask for its type using GetType() would be fine, but not necessary) since i just want to dump it in xml using ToString(). Any suggestions? Thanx.
